Gaius,

Thanks for your prompt reply.

Your build script throws a whole different light on the problem. Now I
see the necessary configure options.

Please bear in mind I'm a simple mechanical engineer, having never done
a compile of this complexity before.

OK I have a successful make.

Then I do
$ cd GM2/scratch-area/build-4.7.3
$ make install

${HOME}/opt is now populated.

$ export ${PATH}:/home/brad/opt/bin

$ cd /home/brad/GM2/scratch-area/gcc-4.7.3
+gm2-git-latest/gm2/gcc-versionno/gcc/gm2/examples/hello/

$ gm2 -g -I. -fmakeall hello.mod
/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3gm2 -c -fmakeall0
-B/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3 -g -fonlylink
-fobject-path=. -ftarget-ar=/usr/bin/ar -ftarget-ranlib=/usr/bin/ranlib
-fmakeall -I. -I/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/gm2/pim
hello.mod
make: /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3gm2: Command not
found
make: *** [hello.o] Error 127

Looks like a Makefile.in error. Missing / before gm2 ?

I'm now clueless. What did I miss?
